IBM zSeries © 2004 IBM Corporation Foil50 Backup Application Failure Application Processing RPO Determining the cost vs. RTO recovery curve is the key to selecting proper solution(s) Business Continuance Objectives  Determine your Objectives for Business Continuance (by application) Recovery Time Objective (RTO) –how long can you afford to be without your systems? Recovery Point Objective (RPO) –when it is recovered, how much data can you afford to recreate? Network Recovery Objective (NRO) –how long to switch over network?  Determine cost / recovery time curve If I spend a little more, how much faster is Disaster Recovery? If I spend a little less, how much slower is Disaster Recovery?

The workshop will look at the site-to-site connectivity necessary to implement GDPS and identify the high level tasks that will be needed to implement.  Business Continuity Solution Workshop This program is designed to introduce the elements of IBM's products and services that form a Business Continuity Solution. Your time will be divided between interactive presentations tailored to your specific requirements and "hands on labs" that allow you to actually experience the capabilities of each element. Over the course of three days at our Washington System Center you will explore topics such as: Disk and Tape Copy Services, Network Options, Server Considerations, System Performance Planning, and Implementation Services.  BCRS Business Continuity Health Check The Health Check is an independent review that creates an action plan addressing continuity issues such as existing capabilities, costs, future technology, and resource requirements.  I/O Bandwidth Analysis IBM will use trace data collected from the customer environment to determine the requirements to configure and implement Remote Copy. IBM will create a written report of the I/O Sizing and Bandwidth Analysis of your existing environment. The report will include an analysis of your full mainframe DASD environment, as well as an analysis of a subset of that environment representing the minimum DASD required to support Remote Copy.
